3 Claims.

1 This invention relates to hinges for doors particularly of the typeused in residences, apartments and the like, and in particular a hingehaving a hinge plate adapted to be mounted on a door jamb or frame, asmall casing adapted to be mounted on a door and having a boltadjustably held therein with the bolt having an extended tubular headpositioned to receive a hinge pin of the hinge plate, and a cam alsopositioned on the hinge pin and having a beveled surface positioned toextend into openings in the casing of the door whereby rotation of a nutin the casing and threaded on the bolt in one direction draws the doortoward the hinge plate with the door riding upwardly on the beveledsurface of the cam.

The purpose of this invention is to provide an adjustable door hinge inwhich a door is adjusted vertically and horizontally with the sameadjusting means.

Various attempts have been made to obtain adjustments between the platesof a door hinge particularly in frame construction where settling of abuilding causes a door to rub or bind on one corner and althoughdifferent types of hinges have been provided for this purpose it isdifcult to provide an adjustable hinge in which the appearance thereofis not objectionable. With this thought in mind this inventioncontemplates an adjustable hinge having a conventional hinge plate withelongated bolt holes therein and having a hinge pin extendedtherethrough, a small casing having a bolt with a tubular head mountedon the hinge pin and in which the parts may readily be shifted topositions on the opposite side of the center for reversing the hinge.

The object of this invention is, therefore, to provide means forforming' an adjustable and reversible hinge whereby the parts mayreadily be mounted on a door and jamb in place of a conventional hinge.

Another object of the invention is to provide an adjustable door hingein which the parts are readily adjustable so that the hinge may be usedon either side of the door.

A further object of the invention is to provide an adjustable reversiblehinge which is of a simple and economical construction.

With these and other objects and advantages in View the inventionembodies a hinge plate having elongated screw or bolt holes therein withhubs at the ends, a hinge pin extended through the hubs of the hingeplate, a bolt having a tubular head positioned on the hinge pin with thepin extended through the head, a cam having a beveled surface alsopositioned on the hinge pin and a, small casing having extended sectionsat one end and openings having beveled surfaces therein positioned tocoact with the beveled surface of the cam and having means for mountingthe bolt whereby rotation of a nut thereon adjusts the position of thetubular head in relation to the end of the casing.

Other features and advantages of the invention will appear from thefollowing description taken in connection with the drawings wherein:

Figure 1 is an elevational view showing the improved hinge with thehinge plate, pin, cam and bolt shown in elevation, and with the casingin which the bolt is mounted shown in section.

Figure 2 is a sectional plan through the improved hinge taken on line 22 of Figure 1 and showing the hinge turned through an angle of degrees.

Figure 3 is a sectional view of the hinge taken on line 3 3 of Figure 1.

Figure 4 is an elevational view looking toward the end of the casingadjacent the hinge'plate and showing the bolt of the casing in section.

Figure 5 is a detail showing parts of the casing, hinge pin and hingeplate with the parts shown in section and showing a cam on the hinge pinextended through an opening in the end of the casing.

Figure 6 is a detail showing a cross section through the adjusting nutthat is threaded on the bolt of the hinge.

Figure '7 is a vertical section through the head of the bolt which isextended from the casing.

Referring now to the drawings wherein like reference characters denotecorresponding parts the improved adjustable and reversible hinge of thisinvention includes a hinge plate I0 having hubs I I and I2 thereon, abolt I3 having a tubular head I 4 through which a hinge pin I5 extends,a cam I6 having a beveled surface I'I, and adjusting nut I8 havingspaced openings I9 therein and a casing 20 having a base 2l with webs 22and 23 between which the nut I8 is positioned, and also having an endwall 24 with notches 25 and 26 therein into which the end of the cam Iiiextends with a beveled surface I'I of the cam alternately engagingbeveled surfaces 2l and 28 in the inner ends of the notches 25 and 26.

The hinge plate IIJ is provided with elongated screw openings 29 throughwhich screws SIB extend for attaching the hinge plate to a door jamb, asindicated by the numeral 3l and, as illustrated in Figure 2, theopenings 29 are provided with beveled surfaces in both'sides of thehinge plate.

The hinge pin I5 is provided with a head 32 and with the parts assembledthe pin extends through E the tubular head I4 of the bolt I3 and alsothrough the opening 33 in the cam i6.

IThe base 2i of the casing is adapted to ce attached to a door 3d withscrews 3%, and with the parts positioned as illustrated in Figure 1, thebolt i5 extends through the webs 22 and 23 and also through a guide web35 which is spaced from the end wall 24 of the base.

The casing or cover 2% is positioned over the base and the outer end ofthe casing is provided with a flange 31 by which the casing is held inposition by screws 38.

With the parts arranged in this manner the hinge is readily mounted on adoor with the hinge plate Il'secured to the jamb and the casing 20, withthe bolt I3 therein, mounted on the door and upon rotation of the nuti8, which is threaded on the bolt I3 and positioned between the webs 22and 23, the door is moved toward the hinge plate or away from the plate,and either movement the door rides on the bevele. surface i1 of the camHi moving the door upwardly as it is drawn toward the hinge plate anddownwardly as it moves away from the hinge plate.

In order to use the hinge on the opposite side of the door it is onlynecessary to reverse the position of the cam i6, placing the cam at theopposite end of the head I4, and also reversing the position of thecasing 20 with the bolt i3 which extends through an opening 39 in theend wall 24 of the base thereof, and with the parts reversed, or turnedover, the hinge is placed on the opposite side of the door.

It will be understood that modicatiens may be made in the design andarrangement of the parts without departing from the spirit of theinvention.

What is claimed is:

1. A hinge having a hinge plate with hubs on one edge, a hinge pinmounted in the hubs on the edge of the hinge plate, a casing havingspaced notches therein adapted to be mounted on a door, portions of thecasing located at one of the ends of the notches being beveled a bolthaving a tubular head mounted in the casing with the head extendedtherefrom and located with the head positioned to receive the hinge pin,and a cam having a hub with a beveled surface extended therefrom alsomounted on said hinge pin and positioned to engage the beveled surfaceof the casing at the end of one of said notches means for horizontallyadjusting the casing in relation to the cam, whereby the cam coacts withthe casing for adjusting the casing vertically in relation to the hingeplate.

2. A hinge as described in claim 1, wherein the casing and bolt aresymmetrical so that the positions of the casing, bolt and cam arereversible whereby the hinge is adapted for use on either side of adoor.

3. A door hinge as described in claim 1, wherein the casing includes abase having an end plate in which said notches are located and in whichan opening through which the bolt extends is provided between thenotches, and in which the casing is also provided with spaced websbetween which a nut having spaced openings in the peripheral surface,and which is threaded on the bolt, is positioned.
